Rubber circle, the rubber circle are arranged in the side of the plug and are bonded second blind hole and third blind hole.

Optionally, the axisymmetrical of second blind hole, first blind hole opposite with the third blind hole.

Optionally, the one-way exhausting device further comprises sealing ring；

The side for closing on one end with first blind hole of the plug is provided with seal groove；

The sealing ring is arranged in the seal groove.

Optionally, the side of the one or both ends of the plug has external screw thread.

Optionally, it is provided with opening on the rubber circle, and there is accommodating chamber in the rubber circle；

The single exhaust device further comprises deformation sheet, and the deformation sheet is adapted for placement in the accommodating chamber.

Optionally, the quantity of the deformation sheet is multiple.

At least there are following advantageous effects in the application:

The one-way exhausting device size of the application is smaller, the device can be arranged in limited structure space, effectively It realizes and internal extra gas is discharged to outside, meanwhile, hinder external air or dust to enter interiors of products, product installation Simply, occupied space is smaller, and reliable operation, the service life is higher, significantly reduces use cost.Machine suitable for reciprocating motion Structure has extremely strong market application value.

Specific embodiment

To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.In the accompanying drawings, identical from beginning to end or class As label indicate same or similar element or element with the same or similar functions.Described embodiment is the application A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use In explanation the application, and it should not be understood as the limitation to the application.Based on the embodiment in the application, ordinary skill people Member's every other embodiment obtained without creative efforts, shall fall in the protection scope of this application.Under Face is described in detail embodiments herein in conjunction with attached drawing.

In the description of the present application, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute The orientation or positional relationship shown is merely for convenience of description the application and simplifies description, rather than the dress of indication or suggestion meaning It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the application The limitation of range.

It is described in further details below with reference to aircraft of each attached drawing to the application.

Fig. 1 is the structural schematic diagram of the one-way exhausting device in one embodiment of the application.

Fig. 2 is the use schematic diagram of one-way exhausting device shown in FIG. 1.

One-way exhausting device as shown in Figures 1 and 2 includes plug 1 and rubber circle 5, and 1 one end of plug has to another The first blind hole 2 that extreme direction extends, the side of plug have the second blind hole 3 being connected to the first blind hole 2 and with the first blind hole The third blind hole 4 of connection；Rubber circle 5 is arranged in the side of plug 1 and is bonded the second blind hole 3 and third blind hole 4.

The one-way exhausting device size of the application is smaller, the device can be arranged in limited structure space, effectively It realizes and internal extra gas is discharged to outside, meanwhile, hinder external air or dust to enter interiors of products, product installation Simply, occupied space is smaller, and reliable operation, the service life is higher, significantly reduces use cost.Machine suitable for reciprocating motion Structure has extremely strong market application value.

Referring to Fig. 1 and Fig. 2, in the present embodiment, axis pair of second blind hole 3 with third blind hole 4 with respect to the first blind hole 2 Claim.

In the present embodiment, one-way exhausting device further comprises sealing ring 6；Plug 1 is closed on the first blind hole 2 The side of one end is provided with seal groove；Sealing ring 6 is arranged in the seal groove.

Referring to Fig. 1 and Fig. 2, in the present embodiment, the side of the one or both ends of plug has external screw thread.

Referring to Fig. 1 and Fig. 2, in the present embodiment, opening is provided on rubber circle, and there is accommodating chamber in rubber circle；It is single Item exhaust apparatus further comprises deformation sheet, and deformation sheet is adapted for placement in accommodating chamber.

Referring to Fig. 1 and Fig. 2, in the present embodiment, the quantity of the deformation sheet is multiple.

Referring to fig. 2, internal gas flows to B mouthfuls from A mouthfuls, and rubber piston ring can be caused to expand after pressure reaches certain value, Gas is discharged from the gap of expansion；After internal not extra gas, rubber piston ring will be fitted closely with plug, meanwhile, Due to being equipped with sealing ring at the product with installation, external air or dust is caused to cannot be introduced into interiors of products, from realizing this Device can prevent extraneous gas or dust from being externally entering interiors of products.The device is connected by screw thread and other products It connects.

The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims It is quasi-.
